This application claims priority to U.S. Patent Provisional Application Nos. 61/804,599 and 61/804,612, both filed on Mar. 22, 2013, the entire contents of which are hereby incorporated by reference.

FIELD OF THE INVENTION

The present invention relates generally to brackets configured to be detachably connected to a shelving unit and support shelves.

BACKGROUND

Storage racks and shelving units are commonly used to store a variety of different articles, such as tools and equipment in a garage (e.g., drills, brooms, shovels, extension cords, etc.), in an organized and readily accessible manner. Typical storage racks include left and right end support units and front and rear crossbeams extending between the end support units. Together, corresponding front and rear crossbeams extending between the end support units define a frame configured to support a shelf for storing various articles. Typically, each end support unit includes front and rear vertical support members and cross braces, both horizontal and diagonal, interconnecting the front and rear vertical support members.

One common type of storage rack known in the art is a “boltless” rack, in which at least some of the members of the rack are configured to be assembled without the use of permanent mechanical fasteners. In some conventional boltless racks, the members of the end support units are permanently coupled together, such as by welding or riveting, and the crossbeams are detachably connected to the vertical support members of the end support units. Typically, the vertical support posts include a series of apertures, such as wedge-shaped slots or keyhole-shaped openings, configured to detachably receive interconnecting members, such as rivets or lances, on opposite ends of the cross beams. Accordingly, boltless racks are configured to permit easy assembly and disassembly of the storage rack or shelving unit without the use of tools, and to permit compact and economical shipment of the unit. An example of a boltless shelving unit is shown and described in U.S. patent application Ser. No. 13/360,543, entitled “Modular Rack Assembly,” the entire contents of which are hereby incorporated by reference.

Typically, storage capacity is limited by the number of storage racks, and additional storage racks had to be purchased to increase the user's storage capacity. However, purchasing a large number of storage racks can be cost prohibitive. Additionally, the space between existing storage racks is typically unused or underutilized space.

Attempts have been made to solve the problem of unused or underutilized space between existing storage racks. For example, U.S. Patent Application 2009/0241812A1 to Liu discloses a shelf that is extendable along a left and right direction. However, extending the Liu shelf requires complicated assembly of many pieces including a plurality of bamboo-shaped pipes, clamping pieces, several different types of bolts, and seamless cone sleeves. Furthermore, extending the shelf may be physically burdensome for some users because it requires steps of tightening bolts.

Another approach uses an extendable shelf assembly. For example, European Patent No. 1030576 to Hardy discloses an extendable shelf where the shelf frame can slide between a plurality of fixed positions along an extender. While Hardy's slidable shelf may enable a user to use a space in a flexible manner, Hardy fails to contemplate using the extendable shelf to connect between existing shelves. Furthermore, sliding shelves and their installation can be cost-prohibitive.

Thus, there is still a need for a shelf assembly system, which enables a user to utilize or convert space between two storage racks into usable storage space more efficiently.

DETAILED DESCRIPTION

The following discussion provides many example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.

The present invention relates to support brackets configured to be detachably connected to boltless shelving units. The brackets of the present invention are configured to increase the storage capacity of two closely spaced storage racks by utilizing or converting the space between the two storage racks into usable, organized storage space. In particular, the brackets are configured to increase the storage capacity of the existing storage racks by supporting crossbeams and shelves extending between the two shelving units. The support brackets are preferably repositionable along the shelving units such that the height of the shelves and the spacing between adjacent shelves can be selected to accommodate various shaped and sized articles, such as tools and other equipment commonly stored in a garage.

Referring now to the embodiment illustrated in FIG. 1A, two closely spaced existing storage racks 100, 101 are illustrated. Each of the storage racks 100, 101 includes left and right end support units 102, 103, respectively, interconnected by front and rear crossbeams 104, 105, respectively. Each end support unit 102, 103 includes front and rear vertical support posts 106, 107, respectively, and horizontal braces 108 extending between the front and rear vertical support posts 106, 107 (i.e., front ends 109 of the horizontal braces 108 are connected to the front vertical support posts 106 and rear ends 110 of the horizontal braces 108 are connected to the rear vertical support posts 107). In the illustrated embodiment, each end support unit 102, 103 includes five horizontal braces 108, although it will be appreciated that the end support units 102, 103 may have any other suitable number of horizontal support braces 108, such as between two and ten or more, depending upon the desired storage capacity of the storage racks 100, 101 and the shape and size of the various articles the storage racks 100, 101 are configured to support. In another embodiment, the end support units 102, 103 may also include diagonal braces extending between the front and rear vertical support posts 106, 107, respectively. In the illustrated embodiment, the horizontal braces 108 are boltlessly and detachably connected to the vertical support posts 106, 107, although it will be appreciated that the horizontal braces 108 may be connected to the vertical support posts 106, 107 by any other suitable means, such as mechanical fastening or welding.

With continued reference to FIG. 1A, each of the vertical support posts 106, 107 is a beam having two generally orthogonal legs 111, 112 (i.e., each of the vertical support posts 106, 107 includes a front leg 111 and a side leg 112 extending rearward from the front leg 111). Together, the legs 111, 112 define a beam having an L-shaped transverse cross-section. It will be appreciated, however, that the vertical support posts 106, 107 may have any other suitable shape, such as a U-shaped or Z-shaped transverse cross-section. Additionally, in the illustrated embodiment, each of the legs 111, 112 of the vertical support posts 106, 107 includes a plurality of keyhole-shaped openings 113 arranged in a column. As used herein, the term “plurality” shall mean two or more. Each of the keyhole-shaped openings 113 includes a relatively larger upper circular opening 114 and a relatively smaller elongated opening 115 extending downward from a lower end of the larger opening 114 (best shown in FIG. 1B). As described in detail below, contemplated support brackets 116, 117 can be boltlessly and detachably connected to the keyhole openings 113 in the vertical support posts 106, 107.

For each of the two storage racks 100, 101 illustrated in FIG. 1A, opposite ends 118, 119 of the front crossbeams 104 are boltlessly coupled to the front vertical support posts 106 and opposite ends 120, 121 of the rear crossbeams 105 are boltless coupled to the rear vertical support posts 107. It will be appreciated that the storage racks 100, 101 may include any suitable number of crossbeams 104, 105, such as between two and ten or more. Additionally, the crossbeams 104, 105 may be positioned at any suitable elevation along the vertical support posts 106, 107, depending upon the locations of the keyhole-shaped openings 113 in the vertical support posts 106, 107, the desired storage capacity of the storage racks 100, 101, and/or the shape and size of the various articles the storage racks 100, 101 are configured to support. In the illustrated embodiment, the number and elevation of the front and rear crossbeams 104, 105 corresponds to the number and elevation of the horizontal braces 108, although it will be appreciated that the number and elevation of the front and rear crossbeams 104, 105 may differ from the horizontal braces 108.

With continued reference to FIG. 1A, the crossbeams 104, 105 each include a pair of spaced apart upper and lower vertical legs 125, 126, respectively. In the illustrated embodiment, the opposite ends 118, 119 of the upper and lower vertical legs 125, 126 of each crossbeam 104, 105 include interlocking members 127 configured to releasably engage the keyhole-shaped openings 113 in the vertical support posts 106, 107. In the illustrated embodiment, each end 118, 119 of the crossbeams 104, 105 includes two interlocking members 127, although it will be appreciated that each end 118, 119 of the crossbeams 104, 105 may include any other suitable number of interlocking members 127, such as between one and three or more. The crossbeams 104, 105 each also include an upper horizontal flange 128 extending inward from a lower end of the upper vertical leg 125, a lower flange 129 extending inward and upward from an upper end of the lower vertical leg 126, and a vertical flange 130 extending between inner ends of the upper and lower horizontal flanges 128, 129 (see FIG. 1C). Together, the inwardly extending upper horizontal flanges 128 on the crossbeams 104, 105 define a ledge or a frame configured to support a shelf panel 131 or other planar support member. Together, the upper and lower vertical legs 125, 126, the upper and lower horizontal flanges 128, 129, and the vertical flange 130 of the crossbeams 104, 105 define a crossbeam having a generally omega-shaped transverse cross-section. It will be appreciated, however, that the crossbeams 104, 105 may have any other suitable shape, such as a C-shaped or Z-shaped transverse cross-section.

Still referring to FIG. 1A, a plurality of support brackets 116, 117 are illustrated coupled to the vertical support posts 106, 107 of the two existing storage racks 100, 101. As described above, the support brackets 116, 117 are configured to increase the storage capacity of the two storage racks 100, 101 by utilizing or converting the space between the two storage racks 100, 101 into usable, organized storage space. The plurality of support brackets includes both left support brackets 116 and right support brackets 117. As illustrated in FIG. 1A, each left support bracket 116 on one of the storage racks 100, 101 has a corresponding right support bracket 117 on the other storage rack 100, 101. Additionally, in the illustrated embodiment, the corresponding left and right support brackets 116, 117 are located at the same elevation on their respective storage racks 100, 101. The corresponding left and right support brackets 116, 117 are collectively referred to herein as a pair of support brackets 116, 117. Additionally, as illustrated in FIG. 1A, front and rear pairs of support brackets 116, 117 are provided. Together, each front pair of support brackets 116, 117 and each corresponding rear pair of support brackets 116, 117 are configured to support a front and a rear crossbeam 132, 133, respectively, spanning or extending between the two existing storage racks 100, 101. Together, the front and rear crossbeams 132, 133 are configured to support a shelf panel 134 or other planar support member in order to provide a surface to support various articles in an organized and accessible manner. In the illustrated embodiment, six pairs of support brackets 116, 117 are provided (i.e., three pairs of front support brackets 116, 117 and three pairs of rear support brackets 116, 117), although any other suitable number of support brackets 116, 117 may be provided, such as between two pairs of left and right support brackets 116, 117 and ten or more pairs of left and right support brackets 116, 117, depending upon the desired number of shelf panels 134. Additionally, it will be appreciated that the pairs of support brackets 116, 117 may be provided at any suitable elevations along the vertical support posts 106, 107, depending upon the size and shape of the various articles the user desires to store on the shelf panels 134 and the desired accessibility of the articles.

In the illustrated embodiment of FIG. 1A, the crossbeams 132, 133 spanning between the two storage racks 100, 101 have substantially the same configuration as the crossbeams 104, 105 provided on the two storage racks 100, 101, although it will be appreciated that the crossbeams 132, 133 may have any other suitable configuration (e.g., a generally C-shaped or Z-shaped transverse cross-section). Additionally, it will be appreciated that the length of the crossbeams 132, 133 spanning between the existing storage racks 100, 101 is not necessarily equal to the length of the crossbeams 104, 105 provided on the existing storage racks 100, 101, and the crossbeams 132, 133 may be provided in any suitable length depending upon the spacing between the existing storage racks 100, 101. Additionally, opposite ends 135, 136 of the crossbeams 132, 133 include at least one interlocking member 137 configured to detachably engage the support brackets 116, 117, as described in more detail below. As best shown in FIG. 1B, in one embodiment, each end 135, 136 of the crossbeams 132, 133 includes two interlocking members 137. In the illustrated embodiment of FIG. 1B, one of the interlocking members 137 projects forward from the upper vertical leg 125 and the other one of the interlocking member 137 projects forward from the lower vertical leg 126. Each interlocking member 137 includes a relatively smaller shaft portion 138 and a relatively larger head portion 139 on a free end of the shaft portion 138, as illustrated in FIG. 1C.

With reference now to FIG. 1B, each of the support brackets 116, 117 includes at least one interlocking member, described in detail below, configured to enable the support brackets 116, 117 to be boltlessly and detachably coupled to the keyhole-shaped openings 113 in the vertical support posts 106, 107. Additionally, each of the support brackets 116, 117 includes at least one aperture, described in detail below, configured to enable the interlocking members 137 on the ends 135, 136 of the crossbeams 132, 133 to be boltlessly and detachably coupled to the support brackets 116, 117. Accordingly, each of the support brackets 116, 117 is configured to be detachably coupled to both one of the vertical support posts 106, 107 on the storage racks 100, 101 and one end 135, 136 of one of the crossbeams 132, 133.

With reference now to FIGS. 2A and 2B, an embodiment of the right support bracket 117 will be described in detail. As illustrated in FIGS. 3A and 3B, the left support brackets 116 are mirror images of the right support brackets 117 illustrated in FIGS. 2A and 2B. Accordingly, it will be appreciated that the features described below regarding the right support brackets 117 are equally applicable to the left support brackets 116, and therefore the left support brackets 116 will not be described in any additional detail. The right support bracket 117 includes a first body portion 140 coupled to a second body portion 141 along an adjoining edge 142. In the illustrated embodiment, both the first and second body portions 140, 141, respectively, are generally flat rectangular plates, although it will be appreciated that the body portions 140, 141 may have any other suitable shape, such as square, and still fall within the scope and spirit of the present invention. The first and second body portions 140, 141 each include front surfaces 143, 144, respectively, and rear surfaces 145, 146, respectively, opposite the respective front surfaces 143, 144.

With continued reference to FIGS. 2A and 2B, the right bracket 117 also includes at least one interlocking member configured to detachably engage at least one of the keyhole-shaped openings 113 in the vertical support posts 106, 107 of the existing storage racks 100, 101. In the illustrated embodiment, the first body portion 140 of the right bracket 117 includes upper and lower interlocking members 147, 148, respectively, although the bracket 117 may include any other suitable number of interlocking members 147, 148, such as between one and four or more, depending upon the desired load-bearing capacity of the bracket 117. The spacing between the interlocking members 147, 148 on the bracket 117 corresponds to the spacing between the keyhole-shaped openings 113 in the vertical support posts 106, 107 of the existing storage racks 100, 101 (i.e., the interlocking members 147, 148 on the brackets 117 are spaced to align with the keyhole-shaped openings 113 in the vertical support posts 106, 107).

In the illustrated embodiment of FIGS. 1D and 2A, each of the interlocking members 147, 148 comprise rivets having a shaft portion 149 projecting rearward from the rear surface 145 of the first body portion 140 of the bracket 117. The shaft portion 149 includes an interconnected end coupled to the rear surface 145 of the bracket 117 and a free end opposite the interconnected end. The interlocking members 147, 148 also include a head portion 150 coupled to the free end of the shaft portion 149. In the illustrated embodiment, the head portions 150 of the interlocking members 147, 148 each have an outer diameter larger than the outer diameter of the shaft portion 149. Additionally, it will be appreciated that the outer diameter of the head portions 150 is smaller than the larger circular opening 114 in the keyhole openings 113 in the vertical support posts 106, 107 such that the head portions 150 of the interlocking members 147, 148 may be inserted in the keyhole openings 113. Moreover, the outer diameter of the shaft portion 149 is smaller than the smaller elongated opening 115 in the keyhole openings 113 such that the interlocking members 147, 148 can be selectively slid down into smaller elongated openings 115, and the outer diameter of the head portion 150 is larger than the smaller elongated opening 115 of the keyhole openings 113 such that the interlocking members 147, 148 are retained in the keyhole openings 113 in the vertical support posts 106, 107, as shown in FIG. 1B. The coupling of interlocking members 147, 148 with existing keyhole openings advantageously enables a user to install crossbeams 132, 133 between storage racks 100, 101 without requiring tools.

With continued reference to FIGS. 2A and 2B, the right support bracket 117 also includes at least one aperture configured to detachably receive the at least one interlocking member 137 on the ends 135, 136 of the crossbeams 132, 133 spanning between the existing storage racks 100, 101. In the illustrated embodiment, the second body portion 141 of the right bracket 117 includes upper and lower apertures 151, 152, respectively, although the bracket 35 may include any other suitable number of apertures 151, 152, such as between one and four or more, depending upon the desired load-bearing capacity of the bracket 117. Additionally, in the illustrated embodiment, the number of apertures 151, 152 in the second body portion 141 of the bracket 117 corresponds to the number of interlocking members 147, 148 on the first body portion 140 of the bracket 117, although it will be appreciated that the number of apertures 151, 152 in the bracket 117 may differ from the number of interlocking members 147, 148 on the support bracket 117. In the illustrated embodiment, the lower aperture 152 is a keyhole-shaped opening, although it will be appreciated that the lower aperture 152 may have any other suitable shape, such as a tapered wedge shape. Substantially as described above with reference to the keyhole-shaped openings 113 in the vertical support posts 106, 107 of the storage racks 100, 101, the keyhole-shaped opening 152 in the support bracket 117 includes a relatively larger upper circular opening 153 and a relatively smaller elongated opening 154 extending downward from a lower end of the larger opening 153. Additionally, in the illustrated embodiment, the upper aperture 151 is an arcuate notch extending downward from an upper edge 155 of the second body portion 141. In one embodiment, the arcuate notch 151 has substantially the same shape and size as the smaller elongated opening portion 154 of the keyhole-shaped lower aperture 152, although it will be appreciated that the upper aperture 151 may have any other suitable shape, such as a tapered wedge shape.

With continued reference to the embodiment illustrated in FIGS. 2A and 2B, the first and second body portions 140, 141, respectively, are non-planar such that a step 156 is defined along the adjoining edge 142 of the first and second body portions 140, 141, respectively. The step 156 in the support bracket 117 is configured such that the second body portion 141 of the support bracket 117 is co-planar with the front legs 111 of the vertical support posts 106, 107, as illustrated in FIGS. 1A and 1B. Accordingly, the step 156 in the support bracket 117 is configured such that the crossbeams 132, 133 spanning between the two storage racks 100, 101 are in line with the vertical support posts 106, 107. Otherwise, the crossbeams 132, 133 spanning between the two storage racks 100, 101 would be spaced apart by a distance different than the spacing between the crossbeams 104, 105 provided on the storage racks 100, 101. Spacing the crossbeams 132, 133 apart by a distance different than the spacing between the crossbeams 104, 105 provided on the storage racks 100, 101 could result in the shelf panels 131 on the storage racks 100, 101 not fitting on the crossbeams 132, 133 spanning between the storage racks 100, 101 (i.e., the shelf panels 131 on the storage racks 100, 101 may not be interchangeable with shelf panels 134). In an alternate embodiment, however, the first and second body portions 140, 141 of the right support bracket 117 may be substantially co-planar. The co-planar or substantially co-planar bracket enables a user to use a shelf panel 134 having substantially the same width as 131, where the width is defined as a distance between the rear vertical post 107 and the front vertical post 106.

The left and right support brackets 116, 117 may be formed from any suitable process, such as stamping, pressing, machining, molding, or rapid prototyping using additive manufacturing. In one embodiment, the interlocking members 147, 148 are welded to the rear surface 145 of the first body portion 140. In an alternate embodiment, the shaft portions 149 of the interlocking members 147, 148 are inserted through openings in the first body portion 140 of the brackets 116, 117 and the interconnected ends 157 of the shaft portions 149 are deformed, such as by bucking with a rivet gun, to couple the interlocking members 147, 148 to the first body portion 140, as illustrated in FIGS. 2B and 3B. The left and right brackets 116, 117 may be made of any suitably strong and durable material, such as aluminum alloy, steel, plastic (e.g., polyvinyl chloride (PVC) or polypropylene (PP)), or carbon fiber reinforced plastic.

With reference now to the flowchart illustrated in FIG. 4, a method 200 of installing and using the brackets 116, 117 of the present invention to increase the storage capacity of two spaced apart storage racks 100, 101 is presented. In one embodiment, the method 200 includes a step 205 of selecting a desired number of brackets 116, 117 based upon the desired additional storage capacity and the shape and size of the various articles the user desires to store. The method 200 also includes a step 210 of selecting the desired locations of the brackets 116, 117 along the vertical support posts 106, 107 of the storage racks 100, 101. The desired positions of the brackets 116, 117 on the storage racks 100, 101 may be based upon several factors, including the nature of the article(s) the user intends to store and the desired accessibility of the article(s). In some contemplated embodiments, step 205 alternatively comprises instructing a user to select the desired locations of the brackets 116, 117 along the vertical support posts 106, 107 of the storage racks 100, 101, and step 210 alternatively comprises instructing a user to select a desired number of brackets 116, 117 based upon the desired additional storage capacity and the shape and size of the various articles the user desires to store.

The method 200 also includes a step 215 of detachably connecting the brackets 116, 117 to the desired locations along the vertical support posts 106, 107 of the storage racks 100, 101. To attach the brackets 116, 117 to the keyhole-shaped openings 113 in the vertical support posts 106, 107 of the storage racks 100, 101, the method 200 includes a step 220 of inserting the head portions 150 of the rivet interlocking members 147, 148 into the larger, upper circular opening 114 portions of the desired keyhole openings 113, and a step 225 of translating the brackets 116, 117 downward until the head portion 150 of the rivet interlocking members 147, 148 are aligned with the smaller elongated opening 115 portions of the keyhole openings 113, as illustrated in FIGS. 1B and 1D.

The method 200 also includes a step 230 of detachably connecting the crossbeams 132, 133 to the support brackets 116, 117.

While this invention has been described in detail with particular references to exemplary embodiments thereof, the exemplary embodiments described herein are not intended to be exhaustive or to limit the scope of the invention to the exact forms disclosed. Persons skilled in the art and technology to which this invention pertains will appreciate that alterations and changes in the described structures and methods of assembly and operation can be practiced without meaningfully departing from the principles, spirit, and scope of this invention, as set forth in the following claims. Although relative terms such as “outer,” “inner,” “upper,” “lower,” “below,” “above,” “vertical, “horizontal” and similar terms have been used herein to describe a spatial relationship of one element to another, it is understood that these terms are intended to encompass different orientations of the various elements and components of the device in addition to the orientation depicted in the figures.

As used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.

As used in the description herein and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.

Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims

It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
